Plot cards - triggered or passive?

By Laban Shrewsbury, in 2. AGoT Rules Discussion

Probably a dumb question, but is the effect on something like Fury of the Wolf triggered or passive? If I don't wish to have the effect, i.e. kill an opponent's character, take place can I choose for it not to happen by not triggering it?

Suspect it's passive (it doesn't have Any Phase or Response ) and always happens, but just want to be sure.

Yes, the effect is passive. And therefore also takes place before any responses.
